Example setup

This example shows the bare minimum requirements to deploy applications on wasmCloud.

It relies on the Kubernetes default namespace for simplicity.

Install NATS

helm repo add nats https://nats-io.github.io/k8s/helm/charts/
helm upgrade --install -f nats-values.yaml nats nats/nats

Validate installation with:

# make sure pods are ready
kubectl rollout status deploy,sts -l app.kubernetes.io/instance=nats

Install wasmCloud Application Deployment Manager - wadm

helm install wadm -f wadm-values.yaml oci://ghcr.io/wasmcloud/charts/wadm

Validate installation with:

# make sure pods are ready
kubectl rollout status deploy -l app.kubernetes.io/instance=wadm

Install the operator

kubectl apply -k ../../deploy/base

Validate installation with:

# make sure pods are ready
kubectl rollout status deploy -l app=wasmcloud-operator -n wasmcloud-operator
# apiservice should be available
kubectl get apiservices.apiregistration.k8s.io v1beta1.core.oam.dev

Create wasmcloud cluster

kubectl apply -f wasmcloud-host.yaml

Check wasmCloud host status with:

kubectl describe wasmcloudhostconfig wasmcloud-host

Managing applications using kubectl

Install the rust hello world application:

kubectl apply -f hello-world-application.yaml

Check application status with:

kubectl get applications

Managing applications with wash

Port forward into the NATS cluster. 4222 = NATS Service, 4223 = NATS Websockets

kubectl port-forward svc/nats 4222:4222 4223:4223
